Span of flowering and fruiting in kokum accessions

Accessions showed a great variation for flowering and fruiting. In general, there was little variation into the initiation of flowering. The accessions attained 50 percent flowering after 30-45 days from initiation of flowering. Generally, span of flowering spread for 8-9 weeks and fruiting season lasted for two months (Plate 5).

 

Time of initiation of flowering

Flowering was initiated during the first week of December for late and last week of November for mid-season bearers. In the earliest bearer Acc.No. 149, flowering was initiated during 4th week of October. But, for other early bearers (Acc.No. 18, 12, 46, 47, 50, 51, 59, 81, 179) flowering initiated during 1st and 2nd week of November.

Mid-season bearers recorded flower initiation during 3rd and 4th week of November. Late bearers recorded initiation of flowering during 1st or 2nd week of December.

 

Time of 50 percent flowering

Irrespective of the type of bearers, the accessions recorded 50 percent flowering after one month of flower initiation. Early bearers recorded 50 percent flowering during 1st and 2nd week of December.

Mid-season bearers recorded 50 percent flowering during 3rd to 4th week of December. All the late bearers recorded 50percentt flowering during 1st and 2nd week of January.

 

Span of flowering

Total span of flowering ranged from 8-9 weeks after initiation of flowering. For early bearers, flowering was noticed in November-December. In the earliest accession no.149, the span of flowering was from 4th week of October to 1st week of January. For other early bearers (Acc.No. 18, 12, 46, 47, 50, 51, 59, 81, 179), the flowering was recorded from 2nd week of November to 3rd week of January. In mid-season bearers, the span of flowering was noticed from 3rd week of November to 4th week of January. In late bearers flowering span was noticed throughout December and January. Few accessions namely 4, 77, 78, 79 had flowering even up to 1st week of February.

 

Span of fruiting

Harvesting was completed in last week of April to 2nd week of May in early bearers. Those accessions in which, more than 2/3rd of fruits were harvested during 4th week of May were named as mid-season bearers. But 60.82 percent of accessions studied were late bearers, where more than 2/3rd of produce could be harvested only after the onset of monsoons i.e. after 1st week of June. This rendered a huge wastage of fresh fruits owing to the fact that the rind could not be sun-dried after harvest. With the onset of monsoons, the fallen fruits pick up the secondary infection and get wasted.

 

Classification based on bearing

Out of 268 accessions studied for flowering and fruiting, there were early, mid and late bearers. Among them, 38 accessions (14.18 percent) were early bearers, 67 accessions (25.00 percent) were mid-season bearers and 163 accessions (60.82 percent) were late bearers.
Out of 268 accessions studied, Acc.No. 149 (Savoi Kamini-1) which was located in Ponda taluk was the earliest among all for flowering and fruiting, followed by Acc.No.18 (Pernem Keri-1) located in Pernem taluk and Acc.No.179 (Hedode-1) from Sattari taluk.
